In most production cases, you will need to write your own tools. Which is why we’re focused on provide the best tool-use experience in Agno.

The rule is simple:

• Any Python function can be used as a tool by an Agent.

1. Create a python function (optionally using the @tool decorator)
2. Create a Toolkit
